TMDSDOCK28379D: Generating two pulses in one switching cycle using EPWM

Part Number: TMDSDOCK28379D

Hello,

I need to generate two pulses at the EPWM pin in one switching cycle. Additionally, I need a dead band for these pulses. Can I use CMPC and CMPD with dead-band? If yes then let me know,  How to do it.

    Hi Nikhil,

    CMPA and CMPB are used by the action qualifier and counter compare submodules to create events for the EPWM outputs. I would suggest setting up your EPWMs with an up-down count mode, this will give you larger flexibility in setting up actions to give you the two pulses during one EPWM period. Yes, dead-band can be applied to the rising/falling edge of the outputs. 

    Here is a video series of our EPWM module, which can help explain all of the submodules.

    Additionally, please refer to the epwm examples within C2000Ware. 

    Best Regards,

    Marlyn
